Background technology
Varsol oil is the important branch of solvent naphtha, and the property of solvent naphtha is different and different regarding its purposes, selects solvent
Oil should mainly consider its dissolubility, volatility, security.Certainly, different according to its purposes, other properties can not neglect
Slightly, it is sometimes even more important.
Solvent naphtha includes cut and refines two processes.Cut process generally has following three kinds of approach：By normal
Pressure tower is directly cut；Corresponding light straight run fraction is cut into appropriate narrow fraction again；Raffinated oil progress with by catalytic reforming
Fractionation.Various spirit fractions are typically necessary by refined processing.To improve color and luster, stability is improved, removes corrosive goods
Matter and reduction toxicity etc..
